The result shows that the coefficient of friction of GCr15 steel ring against nano-ZrO2 ceramic block is 37.3% less than that against 45# steel block, the wear weight loss of nano-ZrO2 ceramic block is only 0. 76% of that of 45# steel block.

• 结果表明:ZrO2陶瓷比45号钢与GCr15钢对磨的摩擦因数值减少37.；3%25；其磨损量仅为45号钢磨损量的0
